SPEGIFIGATION forming part of Letters Patent No. 748,909, dated January 5, 1 904.

Application liled May 21, 1903. p Serial No. 158,123. (No model.)

To a/ZZ whom t rn/uty con/cern: Y

Be tknown that I, AMnEN GEORGE ABI- ZAID, a citizen of the United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in Locking Mechanism for Car Doors, of which the following is a specification.

My invention relates to improvements in a nickel slot-andfbolt mechanism. for car and other doors; and the object is by such mechanism to automatically operate the door by dropping a nickel in the slot or a ticket the equivalent in weight and size of said nickel by the passengers as the);` enter upon the threshold of the door of the car, by which, the door is made to revolve and open' and admit passengers one at a time, thus dispensing with unnecessary expense of a conductor, the motorman acting as such himself.

To this end the invention consists in the novel construction and arrangement of parts, as will be hereinafter more in detail described and specifically claimed.

I have fully and clearly illustrated my invention inthe accompanyingdrawings, in Which- Figure l is a longitudinal elevation, partly in section, of my device applied to a door. Fig. 2 is a top or plan view of the same, and Fig. 3 is a sectional view of the casing containing the Weights.

Like letters of reference indicate correspending parts in the several iigures.

Referring to the drawings by letters, e designates a wing of a door, of which there may be one ormore secured toand radiating from a central shaft, said door being of the revolving type, the entire door and its revolving shaft. being deemed unnecessary to show herein.

H designates a slot formed in the wing of the door nearits lower portion, through which an annulus H is passed, which serves as a guide for the Wings in the revolution of the shaft carrying the wings and to which they are secured.

l designates a lock secured to the wing of the door and located below the slot H, by means of which the Wings can be securely locked or unlocked by the motor-man when necessary. The unlocking of the wing is ap plicable only to persons entitled to ride free.

J designates a partition provided with a recess J', which incluses the operating parts of the nickel-aud-slot mechanism through the medium of a metallic casing, hereinafter described. This partition J, in which the reof this bar is suspended a weight K and upon the opposite end a counterpoise-weight K2, the pivotj forming a fulcrum upon which the Weightsoperate. The recess in the partition where the meeting edge of the same and the meeting edge of the wing of the door come together may be cut away, so as to enable the weight K to enter `the recess J and lock the door when necessary. This pivot j is also passed centrally through a short bar K, which suspends a weight K' at one end of said bar, and at the opposite end of the bar a counterpoise K2 is suspended, said weights receiving their pivotal movement upon the short bar K as a fulcrum. Secured to the partition is one end of a piece of thin brass,'which serves to cover the lock-opening on one side of the partition, and upon the wing e is secured a duplicate piece, which covers the opposite side of the lock, these pieces of brass not being shown in the drawings, so that when a person enters the door a portion of the weight K' can only be seen, and when the door is closed the locking device is entirely hidden.

L designates a metallic casing located and secured in a recessin the partition, having one of its ends terminating in a tube land a portion of its bottom in a receptacle Z', and in said casing is pivotally and centrally secured a lever L', having a hole in one of its ends which when in its normal position is in equilibrio. The lower portion of the tube Z is projected laterally from the partition in which is contained the nickel-operating mechanism, consisting of a push-rod Z2, a coiled spring Z3, secured to and encircling the same, a dog M, pivotally secured in this lateral portion of the tube Z, having a slot m formed therein, and which engages a pin fm upon ICO the upper end of the push-rod Z2, and which projects the nickel in the receptacle. When smaller pieces of money than nickels are dropped in the tube through ignorance on the part of persons for fares, they will pass` directly through the hole or orifice in the end of the lever and fail to operate the same, and in consequence the fare will not have been paid.

The operation of the devices is as follows: The nickel when dropped in the tube of the casing in its descent to the receptacle is projected by` the dog located in the lateral portion of the tube onto the end of the lever with the nickel thereon downwardly and is deposited in the receptacle. The opposite end of the lever, Which ascends simultaneously in the recess, (shown clearly in dotted lines in Fig. 1,) pushes up the weight with it as far as it will go in the weight-casing and disengages the door from the partition, when said door opens and allows persons to enter the car, the counterpoise regulating the movement of the weight. A spring may be secured to the partition, by which the bolt is kept a slight distance from the lock, so that when the lever strikes the under side of the bolt the same will rise easily. A lamp may be suspended upon a nail in the partition a little above the slot in which the nickel is deposited.

What I claim as new, and desire to secure by Letters Patent, is-

In a door-lock, a partition J, having a recess J a metallic casing seated in the lower part of the recess, a smaller recess formed in the meeting edge of the partition and forming a part of the larger recess J the metallic casing having one of its ends terminating in an inclined tubular depository, the tubular depository in turn at its lower portion terminating in a lateral extension in which are contained the locking mechanism consisting of a push-rod V, projected through a perforation in the end of said extension, a pin lm', secured to the inner end of the push-rod, a dog M having a slot m, in its enlarged portion in which the pin m engages, a coiled spring encircling the push-rod, a partition dividing the dog from the coiled spring upon the push-rod, and through which the latter is also projected and against which the coiled spring bears for operating the dog, a coin-receptacle formed integral with the inclined tubular depository and lateral extension, a coin-lever pivotally secured to the metallic casing having one of its. ends provided with a coin-opening, the housing K, secured to the wing of the door and partly projected Within the small recess formed in the meeting edge of the partition J, a short bar lo, pointed at each end and pivotally secured in the housing K, Weight K' and counterpoise-weight K2 suspended from the ends of the short bar, whereby when the coincontrolled lever is operated by the coin the weight K is forced upwardly in the housing and unlocks the door, su bstantially as herein described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

AMEEN G. ABIZAID.
